Need help with Initial Tune
I just installed a new LS2 stroked to a 402. Have blower on it also with typical goodies. I had a local tuner take my PCM (while it was out of the car) and put in a "get me started tune" that included 60 # injectors. The car started easy enough but soon began an spastic idle with rpms surging and going down. Alot of white smoke coming out the exhaust. It has not thorown any engine codes but I can't even put in gear without stalling out. I'm thinking the fuel mix is way to rich but am looking for ideas guys...I need to be able to gert this thing to Jeff Creech but will not be able to if I can't even drive it onto a trailer....Once Jeff gets it I know he will get it all correct but like I said, any ideas to help me get it running a little better so I can at least drice it a little....

If you just need to be able to run it long enough to get it to the tuner--try running it MAFLESS and in speed Density---If your tuner logged your VE table it should be close enough to idle and run lazily anywhere--IF you are mafless already--try adding % to the desired airflow table--helps eliminate surging and stalling---in the Idle table but affects entire airflow range--
